BAG-FRAME FASTENER.

Application filed August 9, 192?. Serial No. 211.672.

The invention relates to means for efiecting the holding together and release of movable frame members, for example, the closing frames holding a bag or like member which latter is generally of a more or less flexible or pliable material to permit movement of said frame elements, as in the opening of the bag. A general object of the invention is to afford simple and effective latch or holding means for such frame pieces which means, moreover, may be entirely concealed when the said frame pieces are closed. The invention has for its object, also, opening means which may be integral with the frame pieces and are adapted for readily releasing the securing elements when a slight pressure is applied thereto, as by squeezing the same between the thumb and first finger of ones hand.

In the accompanying drawings which illustrate the invention,

Fi 1 is a front elevation illustrating the invention.

Fig. 2 is a plan thereof.

Fig. 3 is a fragmentary perspective view of the bag in opened condition.

Fig. 4 is an enlarged fragmentary transverse section taken on the line fi, Fig. 1 of the drawings.

Referring to the drawings, 10 designates the body portion of a bag'of suitable material and of a more or less flexible nature, the same being suitably suspended from two cooperating and substantially rigid frame pieces 11 and 12, as by securement of its upper ec 'c, for example, in grooves 13 and 14 provided in the under edges of the respective frame pieces. 7

As is the usual practice, provision is made for holding the two frame pieces 11 and 12 together, closing the bag; and in accordance with the invention, the said securing means, together with the means provided for opening the bag thru separation of the securing elements, are of such a nature that the former are entirely concealed when the frames are closed and admit of a ready separation thru the operation of the novel releasing or bagopening members associated with the frame pieces.

To this end,-separable securing elements are located in juxtaposition in the respective pieces 11 and 12 as along their inner walls and are, for example, of the type generally known as snap fasteners. The sockets 15 of these fasteners are accordingly embedded in the inner face of the piece 11 and the studs or buttons 16 thereof in the inner face of the other piece 12. This may readily be effected by piercing the former piece and inserting a socket therein which is securely held thereto by upsetting its outer projecting edge over the outer face of the piece, a finishing button 17 being then cemented over the same to the outer face of thesaid piece. To preserve the symmetry of the appearance of the frames, similar buttons 18 are cemented over the outer face of the other piece, though in this instance the studs 16 do not extend thru a frame piece, but are merely forced into a corresponding recess 19 provided in the inner wall thereof, a tubular flanged post 20 being first driven in and the stud or button 16 then forced thereover. Other expedients will naturally suggest themselves for attaining the positive securement of the said fastener elements in the frame pieces; and I do not wish to be restricted to the particular arrangement herein set forth, it being necessary merely that they shall be so mounted as not to be pulled out from the frame pieces when force is applied to the latter to cause them' to become detachedfrom each other in opening the bag. lit is preferred, also, that the securing elements and their securement in the frame pieces shall be such that said elements are substantially concealed when the frame pieces are attached to each other and held together in closing of the bag.

This closing and holding may be effected in the usual manner of fastening snap fasteners together as by exerting the necessary pres sure thereon thru the frame pieces which carry them. The frame in its closed and secured position presents a finished appearance and a very secure hold is insured by the novel arrangement which also is of such a nature as not to admit becoming accidentally opened, so that its contents are safe guarded.

In order to open the bag when desired, provision is made for rocking the two frames about a fulcrum afforded at their contacting inner faces so as to cause a separation ofthe securing elements carried thereby and releasing of the pieces for opening the bag. To this end, one or more pairs of cooperating wing members or tabs 21 and 22 are associated with the respective frame pieces, projecting outwardly from the upper edge thereof.

These pairs of releasing wings may be variously located along the edge of a frame piece and the same are shown substantiall at the ends of the respective pieces; and w rile two pairs are indicated, it will be understood that a single pair will sufiice in which instance the same might, for example, be located substantially midway of the ends of the frame members. It will be noted, furthermore, that these wings, which are adapted to be grasped between say the thumb and first finger of ones hand, are cut away or displaced from the inner faces of the coopcrating frame pieces substantially from the upper edge of a said piece, for example, by being bevelled upwardly as indicated. The outer face thereof, however, is preferably maintained flush with the corresponding outer faces of the frame pieces.

By thus eliminating or displacing the material along the inner faces of coacting wings, an inward movement of the same becomes possible by squeezing them together in ap plying pressure thereon thru ones fingers. This will result in a rocking of the frame pieces about a port-ion of their coacting inner faces as a fulcrum and serves to withdraw a button 16 from its socket 15 to unlock and release the frames so that access may be had to the interior of the bag.

Thus, by merely pressing on these digital releasing members, the frame may readily and quickly be separated to open the bag carried thereby; and likewise the frame pieces may be effectively held together so that there is obviated the annoyance caused by accidental opening of a bag-at times without the owner bein aware of the same and result ing in loss of the contents. The novel frame and latch device withal presents a pleasing appearance, is readily and simply manipulated and may be constructed at compara tively slight cost but without sacrificing ruggedness.

I claim:

1. The combination with two separable rigid frame pieces; of latching means therefor, comprising cooperating fastening elements held by the respective pieces against withdrawal therefrom and adapted to hold said pieces securely to each other, and means associated with said frame pieces whereby to rock the same and effect disengagement of the fastening elements and detachment of the one frame piece from the other.

2. The combination with two separable rigid frame pieces of latching means therefor, comprising cooperating fastening elements held in the inner faces of the respective pieces against withdrawal therefrom and adapted to hold said pieces securely to each other, and means associated with said frame pieces whereby to rock the same about a portion of their coacting inner faces as a fulcrum and effect a disengagement of the fastening elements and detachment of the one frame piece from the other.

3. The con'ibination with two separable rigid frame pieces of latching means therefor, comprising cooperating fastening elements held by the respective pieces against withdrawal therefrom and adapted to hold said pieces securely to each other, and digital wings extending from the respective frame pieces and capable of movement relatively to each other to rock the said frame pieces to effect a disengagement of the fastening elements and detachment of the one frame piece from the other.

4. The combination with two separable rigid frame pieces of latching means therefor, comprising cooperating fastening elements held by the respective pieces against withdrawal therefrom and adapted to hold said pieces securely to each other, and integral digital wings extending upwardly from the respective upper edges of the frame pieces, said wings being beveled outwardly from said edges upon their respective inner faces.

5. The combination with two separable rigid frame pieces, and a bag hung therefrom of latching means therefor, comprising two separable rigid frame pieces from which the bag is hung, cooperating snap fastener elements held in the inner faces of the respective frame pieces to hold said pieces securely to each other, and integral digital wings extending upwardly from the respective upper edges of the frame pieces whereby said frames may be rocked to disengage the snap fastener elements.

In testimony whereof I aiiix my signature.
